This patch includes one more parameter to nx_build_sg_lists() to skip
the given number of bytes from beginning of each sg list.This is needed in order to implement the fixes for the AES modes to make
them able to process larger chunks of data.Reviewed-by: Joy Latten

The NX driver uses the transformation context to store several fields
containing data related to the state of the operations in progress.
Since a single tfm can be used by different kernel threads at the same
time, we need to protect the data stored into the context.This patch makes use of spin locks to protect the data where a race
condition can happen.Reviewed-by: Fionnuala Gunter

Initialization of cra_list is currently mixed, most ciphers initialize this
field and most shashes do not. Initialization however is not needed at all
since cra_list is initialized/overwritten in __crypto_register_alg() with
list_add(). Therefore perform cleanup to remove all unneeded initializations
of this field in 'crypto/drivers/'.Cc: Benjamin Herrenschmidt
